Y

In certain manufacturing establishments, such as steel mills, material is produced in the form of strips of considerable length. As the strips are produced they are wound roughly onto reels or collapsible mandrels.y These `strips usually require further treatment, such as pickling orannealing, and-the present inventionfhas to do with the preparation of such coiled strips for such subsequent treatment, As will be explained more fully hereinafter, the roughly coiled strip is placed on a platform or table of a machine `known asa hype machine and is subjected to treating coiled strip material to therebyfspa'ce" the adjacent convolutions from eachother and `thus prepare the coil forsubsequent treatment. -Another object of our invention is to provide animproved machine, of the-type' mentioned',`

having a support adapted to receive v-acoil of strip material and arotatableA drive spindle ad-` jacent such support adapted .to be connected with the inner end of the Vstrip'for imparting winding and unwinding torque thereto. L

`Yet another object of .our invention is to provide an improved machine, of the type referred to, wherein thev support for the coil comprises a platform which is tiltable' from fone-position to another. .l 1 n Theinvention may be further briefly surmmarized as consisting in certain combinations and arrangements of parts hereinafter described and particularly set out in the appended claims.

In the accompanying drawlngswe have''shl'iwn'l what we now regard to be a `preferredform of our novel hype machine and detailed reference will be made: to this particularmachine. `It

should be understood, fhowever, thatour invene tio'n'xis'not necessarily "confined to this particular apparatus, but may be embodied in various other machines and apparatus of thischaracter. .y

IniFlgsljZ and3f of the drawings `we have' shown a form of our hyping apparatus; which is very'satisfactory for ordinary vand relatively light duty i'nnpreparing coiled strips' for subsequent treatment; This machine is provided with a suitable frame Ill and a work support II, preferablythough not necessarily, in the form ofia tiltable platform or table mounted on theframe and adapted :to receive the `individual coils of strip; material. The work support II may be constructed with angularly extending legs, yas shown in Fig. 3, one of -which legs'forms the `table-like part or platform l2 andthe other of which forms the coil retaining flange I3; This work supportmay have ashaft I4 mounted in openings of the stifening ribs I5 thereof and may be tiltably.- mounted on the frame I0 by providing j the latter with spaced bearings I6A in which the shaft is adapted -tooscillate Y,

As shea/nannies. 2 and 3 'of the drawingsthe tiltable work support I I is mounted on the fra-me IIJ, so` that the side oredge ywhichc'arries the angularly extending flange I3 projects outwardly beyond the .corresponding sideA or vedge of the frame. This :relative arrangement' between the. work support and the frame permits the retainingangel3 `to ybe swungy downwardly to a coil receiving position, as illustrated in Fig, 3, in which position the face I'I` of the flange I3 is N substantially flush with the surface of'the floor I8..1Theplatform.l2 of the work support may be provided-substantially. centrally thereof with anopening I9 and the face I1 of the-.retaining flange I3 may be; provided with an arcuate coil locatingfrecess 20 at a point substantially laterally opposite such opening.

-A'drive spindle y22 is rotatably mountedon the frame, :I ll adjacent the work support Il for. applying winding and unwinding .torque to the inner endofthe coiled strip which is received on `the work support,This drive `spindle may be mounted in bearingsl and 24,'to extend substantially. .vertically in' coaxial relation with the opening I9 of the platform I2. The upper end of the` spindle may be hollow and provided with internal splines 25 for establishing a driving conn'ection with the member to be driven thereby.

For vdriving `the spindle, 22 we provide power means on lthe frame, preferably inthe formof avariablespeed electric motor' 2l,l which lmay be Vc :onnectecl v with a countershaft 28 .'bya drive chain 29 or the like. The countershaft 28 may be connected with the spindle 22 by means of a bevel gear 30 and a bevel pinion 3l. A manually operable controller 32 may also be provided on the frame IIJ for controlling the speed and direction of rotation of the spindle driving motor 21.

As indicated in the drawings, the work support Il is movable to a position with the platform I2 extending substantially horizontally, in which position the upper end of the drive spindie 22 is accessib-le through the opening i9 for establishing a drive connection between the spindleand the inner end of the strip of the coil supported on the platform. As mentioned above, the work support is also movable about the axis of the shaft I4 to lthe broken line coil-receiving position illustrated in Fig. 3. For moving the work support from one of these positions to the other we provide a rock shaft 33 having a crank arm 34 which is connected with a lever portion 35 of the work support by means of a link 36, The shaft 33 is mounted on Ithe fr-ame in suitable bearings provided therefor and is driven from an electric motor 31 `through aspeed reducing 4device 38. i

The tilting motor 31 may be controlled byssuitable apparatus including a push button 39 and a magnetic switch device 40 for starting the motor. This control apparatus may also include a limit switch device 4I which is associated with.

the shaft 33 and is operable to stop the motor when the work support has been moved to one or the other of its extreme positions. The apparatus for controlling the motor 31 may also include a reversing device 42 to provide for movement of the Work support in both directions.

' In the operation of the apparatus just described, and in carrying out our novel method, the operatorstarts the motor 31 and thereby causes the work support Il to 'be tilted to the broken line position shown in Fig. 3. While the work support is in this position a coil of strip material is placed in the recess 2i) of the 'retaining flange i3 and with an end of the-coil against the platform I2. The operator then reverses the motor 31 to tilt the work support to its full line position shown in Fig. 3, in which position the opening I9 of the support is brought into coaxial relation with the upper end of the drive spindle 22. The coil is then shifted on the platform l2, if this .be necessary, to bring the central opening of the c'oil in substantial alignmentwith the drive spindle 22. The collapsible mandrel or reel upon which the coil was previously wound lis removed from the central opening and a mandrel or core 44 of suitable form is inserted into the coil opening. A suitable form of such mandrel shown in Fig. 4 has a slot 45 or other connecting means thereon for engagement with the inner end of the strip and also has a splined shaft projection 46 adaptedto engage in the splined opening of the spindle 22. When the mandrel 44 has been thus inserted to establisha Winding connection 'between the inner end of the strip and the spindle 22, the main motor 21 is started by the operator to rotate the spindle in a direction to apply Winding torque to the inner end of the strip. The mandrel 44 which is inserted into the opening of the coil is of smaller diameter than the reel initially used in winding the coil, and the Winding torque :being applied to the inner end of the strip causes a. substantially tight-Winding of the strip onto the mandrel 44 thereby reducing the inner vand outer diameters of the coil. This winding of the coil to smaller inner and outer diameters causes relative movement between the adjacent convolutions of the coil, which results in the breaking of any adhesions between the convolutions, and also causes the forming of a coil of more regular shape.

Following this tight-winding of the coil to smaller diameters, the moto-r 21 is stopped and one or more of the outer convolutions of the coil are then manually backed oli or expanded to substantially the outside diameter to which the coil is to be expanded. When this has been done the motor 21 is started but is operated in the opposite` direction to cause the spindle 22 to apply unwinding torque to the inner end of the strip. This causes the convolutions of the coil to be expanded or unwound and thereby spaced apart. vWhen sufficient unwinding torque has been applied to the strip to cause all o-f the convolutions to be thus. spaced apart, the motor 21 is stopped and the expanded coil is now ready to be removed from the hype machine for delivery to the annealing, pickling or other subsequent treatment which it is to receive. k.After the coil has been thus expanded it may be tied at points to prevent shifting of the convolutions and may then be lifted from the platform. by a magnet oriother suitable apparatus for delivery to the station where it is to receive its subsequent treatment.

From the foregoing description and the accompanying drawings it will now be readily understood that we have provided novel apparatus for treating coiled strip material land thereby preparing ther same for pickling, annealing or other subsequent treatment which the material is to receive. It will be understood furthermore that our novel method for treating the coiled material involves the novel steps of successively applying winding and unwinding torque to the inner end of the strip whereby the coil is first reduced to a tight-wound coil of smaller inner and outer diameters and is then expanded -or unwound to move the convolutions outwardly into spaced relation to each other.

While we have disclosed the apparatus of our invention in a somewhat detailed manner. it will be understood, of course, that we do not wishto be limited to the precise arrangements and details of construction herein disclosed, but regard our invention as including such changes and modifications as do not constitute a departure from the spirit of the invention and the scope of the appended claims.
